Replit has introduced an AI software agent capable of building complete applications from scratch. This is not just another copilot code assistant; it's more like an intern software developer who can understand your vision and help bring it to life.
So, what exactly is an AI agent? And why is this so significant? Compared to current AI assistants like ChatGPT or Claude, AI agents are more autonomous and proactive. Current AI assistants respond to specific queries or tasks, whereas AI agents can operate with higher independence, make decisions, and execute complex tasks without continuous user input. They can learn and adapt over time, improving their behavior based on feedback and new information.
Replit's AI agent applies this concept to the field of software development. It can reason about tasks and create its own steps to complete them—such as writing code, setting up environments, and managing deployments.
Introduction
The development tool startup Replit has launched a new AI tool called Replit Agent, which can help users build applications from scratch in minutes. Currently, Replit's paid subscribers can access this tool in advance. And the tool can also be easily used on mobile devices.
Founded in 2016, Replit has established a significant advantage over its competitors by collecting vast amounts of data from developers using its platform. Millions of users have used Replit for coding, testing, and deploying applications, with this data directly feeding into the development of Replit Agent. The AI has been trained on data from every stage of the development workflow, enabling it to complete complex tasks more autonomously and efficiently.
Replit's CEO, Amjad Masad, stated: "We have crossed a threshold. This is not about AI replacing developers, but about greatly enhancing human creativity and making software development more accessible."
This article will provide detailed information about Replit Agent, helping you understand this product comprehensively.
Overview of Replit Agent
Replit Agent is an AI-driven development assistant designed to help users build software projects. It assists users in creating applications from scratch through natural language prompts, making software development simpler for users of all skill levels. Replit Agent is currently in early access, offering limited access to Core and Teams subscribers, with further pricing information to be announced later in 2024.
While other companies focus on code completion or generation, Replit Agent is dedicated to understanding the entire software development lifecycle. It can set up project frameworks, write necessary code, debug issues, and even handle deployments—all while explaining its decisions and collaborating with you in real-time.
The potential impact of AI in software development is enormous. We are gradually approaching a future where software development will be democratized. Entrepreneurs can prototype their ideas in hours instead of weeks. Researchers can build custom tools without extensive programming knowledge. The barrier between imagination and realization will gradually disappear.
Advantages of Replit Agent Over Competitors
Of course, Replit is not the only contender in building AI-driven development tools. Alongside Microsoft and its GitHub Copilot, a wave of emerging startups is reimagining how we create software. For example, Cognition is developing Devin, an AI promising to act as an autonomous software developer, capable of building complete projects from scratch. Meanwhile, Magic recently raised an astonishing $320 million and announced its LTM-2-mini model with a 100 million token context window. Recently, Anysphere's Cursor has gained increasing attention among developers and enthusiasts exploring the potential of AI-assisted programming.
But Replit believes it has a unique advantage, as its platform not only generates code but also handles infrastructure and deployment issues in the development process. For developers, this means less time wasted on repetitive tasks and more focus on creativity. For businesses, this represents a faster and more cost-effective way to bring software to market.
Replit's CEO, Amjad Masad, is convincingly optimistic about the democratization of software development through AI, but it's clear that these advancements will also reshape the industry. As the technology becomes more powerful, many jobs will undergo transformation. Software developers will need to adapt to these changes, focusing on higher-level creative problem-solving, while routine tasks will increasingly be handled by AI agents.
Currently, Replit Agent is available in beta to Replit Core and Teams subscribers.
Even Andrei Karpathy, co-founder of OpenAI and former AI director at Tesla, who has been actively using Cursor for programming, stated that Replit Agent can be classified under the "feel the AGI" category.
Karpathy said, "As mentioned in (Amjad Masad's) post, making actual applications is more than just code; you have to set up the entire environment, deploy, etc. Automating all these other infrastructures will allow anyone to quickly build and deploy entire web applications."
Some say that Cursor will be able to replace software engineering teams or at least reduce their size, while Claude Artifacts might kill app stores, but Replit Agent can almost build everything from landing pages to healthcare applications connected to databases in seconds. This doesn't even require writing a single line of code. Replit's CEO, Amjad Masad, shared some examples on social media 𝕏, where people built a healthcare application in minutes, with the agent fixing errors on its own, a Flask and native JavaScript-based website backed by a real-time postgres in less than 10 minutes, and even a Wordle clone completed in just 2 minutes and 43 seconds.

Replit Agent Usage Tutorial
- Log in to your Replit account (requires a Replit Core or Teams subscription).
- Access the homepage or select Create Repl in the left navigation.
- Enter a prompt describing what you want the agent to build. The prompt should be descriptive and detailed (A good prompt is descriptive and detailed. Imagine you are describing a task that needs to be completed by a teammate. What information must they know to complete the work?).
- Let the agent choose the technology instead of specifying a particular language or framework.
- Inspect and iterate on the plan generated by the agent, editing or deleting recommended steps.
- Track the agent's progress and provide necessary API keys, feedback, or guidance during the build process.
- Test your application and pose follow-up questions as needed.
- Deploy your application to a production environment.
